For each problem, one curved surface is shown restraining a body of static fluid. Compute the
magnitude of the horizontal component of the force and compute the vertical component of
the force exerted by the fluid on that surface. Then compute the magnitude of the resultant
force and its direction. Show the resultant force acting on the curved surface. In each case, the
surface of interest is a portion of a cylinder with the length of the surface given in the problem
statement.
